Yeah, different brushes will have different outcomes and also used in specific steps. It can depend on the technique like how good you are with adapting but certain brushes will either help you or make your life harder. Maybe a “perfect one” for someone will just depend on how much they like the effect of that tool, not necessarily something that is strictly for each person. Unlike foundation shades which need to be perfectly suited for someone.. so if you bought a “wrong one” you can always use them later on for different purposes. :D

Some brushes are big and some are dense and some are thin.. big brushes are oftentimes used for big areas like cheeks or whole face while some smaller brushes are for applying eyeshadow and some are for blending.

For dark circles, I find the SAEM concealer to cover up pretty well and no need for other stuff like foundation or color correctors. It’s very good for beginners and it’s cheap as well and lasts a long time. I don’t even need foundation if I’m using that concealer :D
